What is the most embarassing way your body has betrayed you?

When I was in 7th grade our school gathered both 7th and 8th grades into our small library and were seated on the carpeted floor. Most people sitting with their legs crossed but I am a tall not a very flexible person even back then. So we have our guest speaker talking to us interacting with us and I'm fidgeting around trying to get comfortable on the floor because there isn't much space. I suddenly feel the floor vibrate and heard a really loud noise. As soon as this happens I freeze in then middle of shifting around. I see my crush in front of me with her friend looking back at me trying to contain their laughter but they couldn't. The people around me couldn't believe what just happened. I had to sit there for another half hour.
